Normal Operation
WARNING: Do not disconnect the wire connector at the side air bag module. This is a permanent connection. Doing so may result in air bag accidental deployment, which may result in personal injury.
The restraints control module (RCM) monitors the resistance of the driver side air bag circuit loop and the air bag module igniter at RCM C310b pins 2 and 3. If the resistance is greater than 3.6 ohms, the RCM will store diagnostic trouble code (DTC) B1994 and flash lamp fault code (LFC) 36.
Possible Causes
A high resistance on the driver side air bag circuit can be caused by:
- damaged wiring on circuit 30S-JA37 (RD/GN).
- damaged wiring on circuit 31S-JA37 (BK/GN).
- damaged driver side air bag module.
- a faulted RCM.
